Can't get on Survival server

Every time I right-click the survival server pickax it takes me to the survival server for 1 second, then it kicks me out and it says "The server you were on went down..." I tried going on 5 times, but, it didn't work so I restarted minecraft, it still didn't work, so I restarted my laptop, it still didn't work, there seems to be no solution for this in my part. but I know you guys can do something about it. I don't want to lose my survival server plot I worked so hard on it so if you can please just help me i'll appreciate it.
